Named Minikube Cluster is not recognized as local Kubernetes cluster

[johnnypea]

I run vcluster in Minikube localy for testing purposes and I can't get local image building working.

Please, could you check my config? I'm not sure about "buildKit" and "docker" parts in images section.

vars:
  - name: REGISTRY
    value: "myapp.local" 

images:
  php:
    image: ${REGISTRY}/php
    dockerfile: api/Dockerfile
    context: api/
    build:
      buildKit: 
        inCluster: {}
        skipPush: true
      docker:
        options:
          target: symfony_php

deployments:
- name: app
  helm:
    componentChart: true
    values:
      containers:
      - name: php-container
        image: ${REGISTRY}/php

Tags are the same but it doesn't use local image, why?

    state:

        reason: ErrImagePull

It looks like the images are build with local docker daemon on my host not in the actual cluster.

This config works with Minikube without BuildKit and vcluster.

Thank you. 🙏

@johnnypea Thank you for the issue. We'll look into this.

[pratikjagrut]

We made a mistake in doc. I think the correct config should be like below:

 php:
    image: ${REGISTRY}/php
    dockerfile: api/Dockerfile
    context: api/
    build:
      buildKit: 
        inCluster: {}
        skipPush: true
        options:
          target: symfony_php

Could you please try this out?

[johnnypea]

@pratikjagrut thanks, but still the same problem

  - image: myapp.local/php:YPbQNky
    imageID: ""
    lastState: {}
    name: php-container
    ready: false
    restartCount: 0
    started: false
    state:
      waiting:
        message: 'rpc error: code = Unknown desc = Error response from daemon: Get
          "https://myapp.local/v2/": dial tcp: lookup myapp.local: Temporary failure
          in name resolution'
        reason: ErrImagePull

[warn]   Pod intraspace/app-0 has critical status: ErrImagePull. DevSpace will continue waiting, but this operation might timeout
[fatal]  error deploying: in hook 'wait for selector app.kubernetes.io/component=app': timed out waiting for the condition

It looks like it doesn't or can't use local image.

@johnnypea maybe try to use imagePullPolicy: Never as this might help

[johnnypea]

@FabianKramm didn't help :(

  - image: myapp.local/php:fMyzTrj
    imageID: ""
    lastState: {}
    name: php-container
    ready: false
    restartCount: 0
    started: false
    state:
      waiting:
        message: Container image "myapp.local/php:fMyzTrj" is not present
          with pull policy of Never
        reason: ErrImageNeverPull

[johnnypea]

@FabianKramm @pratikjagrut images are created for my local Docker not one in Minikube when used with vcluster. It works as expected with "minikube" context". Is there some configuration I should set?

[johnnypea]

And I don't know if this could be related but I noticed this kind of errors in my vcluster console:

[FabianKramm]

Ah yeah, since minikube has its own docker daemon, devspace pushes the image to docker instead of the minikube daemon, which is why the image cannot be pulled. A workaround currently would be to use minikube as context name or expose the docker daemon before running devspace with:

minikube docker-env
devspace dev

[johnnypea]

@FabianKramm but shouldn't Buildkit config do the trick?

      buildKit: 
        inCluster: {}

[FabianKramm]

@johnnypea not sure but I believe pushing the image still doesn't reach the correct docker daemon

I am having a related problem. I want to deploy multiple clusters to do some testing between clusters however when I give my minikube cluster a unique name it does not get picked up by devspace.

$ minikube profile list

|----------------|-----------|---------|---------------|------|---------|---------|-------|
|    Profile     | VM Driver | Runtime |      IP       | Port | Version | Status  | Nodes |
|----------------|-----------|---------|---------------|------|---------|---------|-------|
| test-domain-1  | hyperkit  | docker  | 192.168.64.12 | 8443 | v1.23.3 | Running |     1 |
| test-network-1 | hyperkit  | docker  | 192.168.64.11 | 8443 | v1.23.3 | Running |     1 |
|----------------|-----------|---------|---------------|------|---------|---------|-------|

I tried manually sourcing the docker-env but it doesn't seem to matter.

$ eval $(minikube -p test-network-1 docker-env)
$ devspace deploy -p network -n test-network-1

....
[tailscale] ------
[tailscale] error: denied: requested access to the resource is denied

I also tried inCluster: {} but I got a different error about needing to setup a builder or something?

I have also tried to use k3s / k3d but I don't know how to set the private docker registry settings for it either, so I get the push errors. When I do a docker login it pushes to live docker hub which is not what I wanted.

It would be great if there was a way to use more than 1 local cluster for development somehow.
